Description

Technical Field

[0001] The present invention relates to the technical field of pipeline repair, and particularly relates to a stainless steel quick-lock pipeline repair device and a construction method thereof. Background Art

[0002] Underground pipelines are mainly used for the discharge of urban sewage. Since many underground pipelines have been laid for a long time, during long-term operation, these pipelines are locally damaged due to corrosion, overloading, foundation settlement or human factors, etc. After the existing pipelines are repaired, they only have the effect of simple repair and do not have the effect of bearing weight, which easily causes the phenomenon that the repaired part cannot bear too much pressure, resulting in secondary damage and affecting the use of the pipeline.

[0003] Therefore, this solution specifically proposes a stainless steel quick-lock pipeline repair device and a construction method thereof to solve the above problems. Summary of the Invention

[0004] The main purpose of the present invention is to provide a stainless steel quick-lock pipeline repair device and a construction method thereof, aiming to solve the technical problem of rapid pipeline repair.

[0005] To achieve the above object, the technical solution of the present invention is realized as follows: A stainless steel quick-lock pipeline repair device includes a stainless steel sleeve and a moving device for sending the stainless steel sleeve into the pipeline. The stainless steel sleeve is composed of three stainless steel ring pieces connected by a locking mechanism. The locking mechanism includes an insertion bar provided on the inner arc surface of the stainless steel ring piece and an insertion sleeve adapted to the insertion bar. A plurality of triangular grooves are equidistantly arranged on one side of the insertion bar, and a triangular locking block adapted to the triangular groove is provided on the inner wall of the insertion sleeve. A rubber sleeve is sleeved on the outer surface of the stainless steel sleeve. A pressing spring is provided on one side of the triangular locking block, and the other end of the pressing spring is fixedly connected to the inner wall of the insertion sleeve.

[0006] Further, the moving device includes a moving bracket. An inflatable airbag is provided on the outer periphery of the moving bracket. The stainless steel sleeve is sleeved on the outer periphery of the inflatable airbag. Rotating rods are circumferentially and equidistantly rotatably connected to the outer peripheries of both ends of the moving bracket. A moving wheel is provided at the end of the rotating rod away from the moving bracket. A support spring is provided on the outer surface of the rotating rod, and the other end of the support spring is fixedly connected to the outer periphery of the moving bracket.

[0007] Further, an air charging pipe communicating with an external air charging device is provided on the outer surface of the inflatable airbag. Towing ropes and cameras are fixedly connected to both ends of the moving bracket.

[0008] Further, a kidney-shaped sliding hole is provided on the outer surface of the insertion bar, and a jack is provided outside the insertion sleeve.

[0009] A construction method for repairing a pipeline with a stainless steel quick-lock includes the following steps:

[0010] S1. Plug the precipitation, and plug the upstream outlet pipe and the downstream inlet pipe of the pipeline section to be repaired.

[0011] S2. Clear and wash the pipeline to be repaired.

[0012] S3. Sleeve the stainless steel sleeve on the outer surface of the moving device, and then sleeve the rubber sleeve on the outer surface of the stainless steel sleeve.

[0013] S4. Use the moving device to transport the stainless steel sleeve and the rubber sleeve to the internal repair position of the pipeline.

[0014] S5. Inflate and repair. Slowly inflate the inflatable airbag to slowly expand the stainless steel sleeve and make it closely adhere to the inner wall of the original pipeline.

[0015] S6. After confirming that the stainless steel sleeve is fully opened, release the pressure of the inflatable airbag and then withdraw it.

[0016] Furthermore, the pressure of the inflatable airbag shall not damage the locking mechanism of the stainless steel sleeve, and it should be controlled at 0.35 MPa to 0.40 MPa.

[0017] The beneficial effects of the present invention are as follows: First, sleeve the stainless steel sleeve on the outer periphery of the moving device, insert the insert bar into the insert sleeve, and use the triangular clamping block and the triangular groove to fix the insert bar under the action of the abutting spring to complete the connection between the three stainless steel ring pieces. Then, use the moving device to send the stainless steel sleeve into the pipeline to be repaired. After the stainless steel sleeve is transported into the pipeline to be repaired through the moving device, inflate the inflatable airbag to expand the stainless steel sleeve, and use the pressure to make the stainless steel sleeve repair the repair area through the rubber sleeve to achieve the purpose of rapid repair. And through the stainless steel ring pieces, insert bars and insert sleeves, the stainless steel sleeve has a certain load-bearing capacity, avoiding the phenomenon of secondary damage to the pipeline due to inability to bear the load.
